PC won't turn on after motherboard swap

[gbench]

Hi! I just got a new (actually used) motherboard and cpu (1150). So after 3 hours of sweat the new mobo was in the case (first time). When I pushed the power button, nothing happened. No fans turning on, no lights on the mobo showing. Before I took out old mobo I counted the wires attached and got 7 + sata cables. I also used mobo manual. Right now there are exactly 7 wires attached (that 8-pin bundle counted as one wire (jfp1). Is there a possibility that I misplaced the wires? Or maybe I created static electricity and fried my mobo? PSU can't be the case because it worked just fine before the mobo swap. Mobo is H81M-P33, cpu i5 4440, psu fortron fsp hexa 500 w.

Might help if we knew what motherboard you're talking about, but a wild guess would be that "8-pin bundle" doesn't match the motherboard's front panel connections.

Mobo is MSI H81M-P33. This 8-pin bundle includes power switch, power led, reset switch, hdd led (all "+" and "-").

Sorry. The above should have read, "motherboard's front panel connections". Check to make sure the pin alignment in the bundle matches the pin alignment on your new motherboard.

I used my mobo manual for connecting the wires. So I am quite certain that they are correctly aligned. I will look it over later today just to make sure.

Edit: I just checked the manual and noticed that reset switch needs different alignment than other wires. I probably didnt notice it yesterday. Could it be the case?

Could be.
